Subject: Added initial experimental support for explicit vectorization.
 Currently only the following platform/operations are supported:  - SSE2
 compatible architecture  - compiler compatible with intel's SSE2 intrinsics 
 - float, double and int data types  - fixed size matrices with a storage
 major dimension multiple of 4 (or 2 for double)  - scalar-matrix product,
 component wise: +,-,*,min,max  - matrix-matrix product only if the left
 matrix is vectorizable and column major    or the right matrix is
 vectorizable and row major, e.g.:    a.transpose() * b is not vectorized with
 the default column major storage. To use it you must define EIGEN_VECTORIZE
 and EIGEN_INTEL_PLATFORM.
